Sustainability In The Coal Industry Statistics 2026

Coal still generated 36% of the world’s electricity in 2022, yet parts of Europe cut coal power by 46% between 2015 and 2022. Behind that shift, the climate and air quality tradeoffs get sharper, from methane leakage across the supply chain to the emissions controls that can dramatically change outcomes at the plant level. We pull together the most telling sustainability statistics so you can see where coal is losing ground and where the biggest emissions challenges remain.

Key Takeaways

In the European Union, power generation from coal fell 46% from 2015 to 2022 (TWh basis)

Methane emissions from the fossil fuel supply chain were estimated at 110 million tonnes of methane (MtCH4) in 2019

Global coal mine methane emissions were estimated at 15.6 MtCH4 in 2020

In 2022, flaring and venting were estimated to emit 7% of global methane emissions

U.S. coal mining methane emissions were estimated at 1.1 million metric tons of methane (MMtCH4) in 2022

Interpretation

Emissions & Impacts Interpretation

Even as coal power declines in the EU with a 46% drop in generation from 2015 to 2022, the emissions footprint remains large since coal still drives high lifecycle greenhouse gases of about 200–300 gCO2e per kWh and methane impacts across the fossil supply chain are substantial at 110 MtCH4 in 2019, with global coal mine methane alone estimated at 15.6 MtCH4 in 2020.
